Insured Cat Losses Hit $3.98 Billion — but Building Costs, Not Storms, Are the Real Premium Driver
The Insurance Council's latest damage bill is $1.7 billion higher than last year, but its chief executive says construction cost inflation, not catastrophe frequency, is now the bigger problem for premiums.
The Insurance Council of Australia's latest Catastrophe Resilience Report puts FY26 (to June 2026) insured catastrophe losses at $3.98 billion across seven declared events, up $1.7 billion on the prior year. The single largest event was the November Queensland/NSW severe storms with hail — 95,692 claims and $2.23 billion in losses — followed by the October/November spring storms ($1.07 billion) and the Victorian bushfires ($598.6 million); smaller declared events included the Bondi Beach terror attack ($600,000), NT flooding ($40.6 million), Queensland flooding ($45.9 million) and Middle East conflict-related claims ($4.1 million). ICA chief executive Andrew Hall's central message was about cost, not frequency: building costs have risen roughly 30% over five years against 24% general inflation, with roof tiles up 77% and windows, plaster, plywood, copper piping, structural steel and cement all up at least 37% — Queensland home construction is now about 45% more expensive than in 2021. Hall said "every insurance claim draws on the same builders," now competing with Olympic Games infrastructure and data-centre construction for labour and materials, and called for "a plan to tackle both the resilience and the costs of housing." Flood losses alone have risen from an average $129 million a year in the 2000s to roughly $2 billion a year since 2020.
Why it mattersThis is the clearest public explanation yet of why premiums keep rising even in years without a single mega-catastrophe — construction cost inflation is now doing as much work on the claims bill as the weather itself, and it's a dynamic no single insurer's pricing model controls on its own.
